-changed back to blackberry after a short stint with the tmobile mda (buggy and annoying....should have stayed with bb!)

-unit starts dropping charge quickly, down to radio off from fully charged in 8-10 hours with light usage.

-exchange at tmobile for new unit

-new unit starts doing the same after about a week....this time i research on this forum and apply all battery saving tips i can find....not using bluetooth, backlight low, no push services....

-no change....exchange the whole thing again!

-all well for a little while, about a week, then same thing happens AGAIN!!!

-i havent changed any settings and i'm a light maybe moderate user....the battery should last for ages.....i've had several other bbs before but never this prob! my husband has the same (8700g) with the same setting, same provider and usage....he has no probs....

-tmobile will not exchange again but say they have to send it off this time.....presumably i will get a refurb back....not happy!

now....is it likely that i have had three faulty units in a row....or am I doing something wrong??
is this a known issue?

any ideas?

i'm at my wits end....bought a car charger as i cant afford for the unit to go off....i'm a homebirth midwife on call and calls CAN'T be missed!!!

Are you always using the same battery? Are you getting a new battery with each unit? What about a new charger with each unit? All factors you should look at. Try charging thru usb on your pc and see if that helps.
